Yep.

I'm starting a new story.

I can't help it. I suck at stopping myself at doing this.

Anyway, there will be some differences from canon, then again I guess that can count for pretty much for any story I make. There will be crossover elements, but if you know me by now, you would have already expected that.

Well, enjoy, or not, I don't care you all have your opinions.

Everything belongs to their respective owners.

Chapter One: Demon Unleashed

Four hundred years ago.

It was during this time when the greatest threat the world has ever known came to be.

The Dragon Civil War had broken out, where the two sides wage war all over Ishgar. There was the side that wanted to destroy the humans and the other who wished to protect them. The war escalated, as both of sides gained heavy casualties. At each turning point, each side would seem to get the advantage before it would even out once again. However, a new force emerge which then took part of the war.

The etherious.

A race of demons created by the dark wizard Zeref himself, who created them in hopes they can end his life once and for all. However the etherious began to meddle with the world itself, and thus the war took an even worse turn. It didn't seem like peace would ever arrive to the continent. It became even worse with the rise of Acnologia, the Dragon of Apocalypse, who went on to attack anyone, either they be human, dragon, or etherious.

However, rumors began to be heard that the dark wizard Zeref began to create a demon with such power that nothing would stand against it. Unknown to the rest of the world, this was his attempted to finally revive his younger brother, who was killed years earlier. After gaining an unknown magic that the world hasn't seen before, the black wizard began to bring back his lost sibling. However, the magic corrupted the younger brother's body, transforming it into the most powerful demon Zeref has ever created.

E.N.D.

Unlike with the rest of his creations, the black wizard gave this demon free will. He wasn't bound to him like the rest were, and thus allowed the demon to do what he pleased, believing that when the time comes, the demon will grant his wish.

However, this would prove to be Zeref's greatest mistake.

E.N.D went on to attack and destroy both the humans and dragons. The eitherious cheered by these assaults by the one they consider their master. With their lord on the field, the war turned to the favor of the etherious.

But then, the unthinkable happened.

To the race of demons horror, E.N.D began to attack the etherious as well. Human, dragon, etherious, no race was spared by the demon's wrath. No side could stand against what the etherious called E.N.D the Fel Demon. Not even Acnologia was able to triumph against E.N.D, as the dragon who became the king of his race was forced to flee.

This showed the three races how dire the situation was, realizing that the world itself could be destroyed by E.N.D. And then, for the first time in Earthland's history, the three races joined forces. Where the sides once wage war on each other, now work side by side against E.N.D. The three races were led by the black wizard Zeref, who led the etherious. The Dragon King Acnologia led the dragons. And a woman named Anna Heartfilia led the humans.

When the Fel Demon appeared once again, the three races attacked the demon with one major assault, hoping for this to be the end of the demon once and for all.

Instead, the attack let to their ruin.

E.N.D massacred the forces that kept on fighting him. The result of the long battle that lasted for days ended up with the near extinction of both the etherious and the dragons. The Fel Demon himself hardly received much damage, which brought depair to the remains of the united forces.

But then, a miracle happened.

Againsts all odds, Zeref, Acnologia, and Anna managed to not only seal the demon away, but also succeeded in splitting him into two beings. The demon himself was imprisoned inside a book and the other half ending up as Zeref's younger brother, Natsu Dragneel.

Then, history went on. The remaining etherious either went into hiding, or were sealed or killed off by the humans and the surviving dragons. Acnologia went on to wipe out the remaining dragons, with only a few managing to survive the dragon king's onslaught. The remaining dragons then took in students, one of them was E.N.D's other half Natsu. With the help of Zeref and Anna, the dragons and the students would go on to be sent to the future in hopes to one day defeat Acnologia. To them, the threat of E.N.D was finally over.

Unfortunately, they could have never been more wrong.

'PRESENT DAY'

The Nine Demon Gates were confused and alarmed.

They were doing their own thing aboard the Cube, but then a loud explosion was heard as the whole of their base began to shake uncontrollably. Believing that some fool or fools dared to attack the Tartaros guild, the group of demons headed to where the throne room where Mard Geer was at. However when they arrived, they were shocked by what they saw. Mard Geer was on the ground; as if something caused him to be knocked down as smoke filled the air. But that wasn't what got them to be surprised.

In the center of the room was a humanoid looking figure that was pure black. His body seemed to be pretty leaned muscular type. Two giant demonic wings were present on the creature's back. Green markings were present on the being's chest, upper arms, and face. Instead of feet, it had hooves. The sides of his face seemed to spike upwards a little bit, giving him a more menacing look. Two demonic horns were present on the figure's head. He even had claws compared to any normal fingers. Then there were his eyes, two eyes that were completely glowing green. While it may look simple, if one were to bore into them, it would be like staring into the abyss itself.

Before any of the etherious could say or do anything about this unknown entity, Mard Geer spoke with disbelief and shock.

"L-Lord E-E.N.D?" He questioned which got the other demons to widen their eyes from Mard Geer's words.

The demon didn't seem too noticed, or more accurately didn't care, as he looked at his hands. He smirked as he turned his attention to the shocked etherious guild.

"…I'll get to you all later." E.N.D spoke to them.

Without warning, E.N.D spread his wings before taking off through the roof above him. A shockwave resulted by the sudden take off of the Fel Demon, causing the other demons to cover there eyes from the large gust of wind. If they were to look at the sky through the hole, they would see the sky had taken a darkish green color, as it thundered.

Now with E.N.D, the Fel Demon was now flying through the sky as he was still grinning.

'Ah… it's so nice to stretch my wings again. With my other half now stuck on that island for a few years, this gives me the perfect time to return to the world.' E.N.D thought to himself as he picked up his speed.

There were so many things the demon wanted to do. But first things first, he's going to pay a little visit to the capital city of Fiore. He had ideas, he wanted to have fun, but he also wants some challenge as well. So for that to happen, certain things need to… change. Crocus was the ideal place to start.

"YES! NOW LET'S HAVE SOME FUN SHALL WE?!" E.N.D shouted with a sadistic smile as he began to laugh manically as he flew to his destination.

'LATER'

Crocus, the capital city of Fiore itself, widely known as the Flower Blooming City. It was currently night as the residents of the city slept peacefully. The only ones who would still be awake at this time would be simple guards as they patrolled the city and the palace.

*BOOM*

Unfortunately the peace would not last as something crashed into the palace, causing a massive explosion that shook the entire building. This woke up the residents of the city, as the explosion could be heard for miles.

In the palace, a young girl with green hair was suddenly awoken due to the noise, and was confuse when she began to hear tons of footsteps of guards outside her room. This was Hisui, the young princess of Fiore. Curiosity taking hold of her, she got out of her bed and went to open the door. Like she guessed, tons of guards were running through the hallway, however the young child didn't know why.

"Hisui!" A voice called out, as she turned to the other side of the hallway to see her dad and Arcadios running to her. Looks of worry were on their faces, which only confused the young girl even more.

"Daddy? What's going on?" She asked him in confusion. The green haired girl didn't understand what was going on.

King Toma and Arcadios didn't answer her as the king grabbed her daughter's hand as they began to run the opposite way where the guards went. Hisui was still confused as to why her dad and Arcadios looked so afraid about something. Why were they running too?

Another loud explosion shook the whole palace once again. As the three managed to arrive in the throne room where more guards were present. Looks of fear were present on their faces. Toma and Arcadios guessed something must have happened.

"What's wrong?" Aracrios questioned then as another explosion shook the building.

"S-Sirs! The ministers! They're all dead!" One of the guards managed to reply with a shaky voice. The king and the knight's eyes widen in shock by what they just heard. Hisui was confused though. What did that mean? Did that mean something bad?

A loud explosion was heard behind them, getting everyone to turn to see the outline of some sort of figure in the smoke. The only thing they could see were the glowing green eyes in the smoke. The mere sight caught everyone to be afraid. Hisui was no exception, as she was only a child which made her fear even worse than the others.

A demonic chuckled was heard from the smoke as the figure was suddenly enveloped in some kind of green fire. This set alarms off in everyone's mind, well expect for Hisui as she didn't understand what was about to happen.

"GET DOWN!" Arcadios shouted as he put himself in front of the king and princess as the demon unleashed a massive blast all around them.

From the outside of the palace, people could see a large pillar of green fire shot up from the building and into the sky. The guards in the streets were trying to keep the citizens calm and safe, but it was to do that when everyone was freaking out.

Back in the castle, Hisui managed to open her eyes after whatever happened was through. However, what she then saw was something no child should witness, and would haunt her for the rest of her life.

Dead bodies littered the remains of the throne rooms. Rubble and boulders covered the whole room as green fire was alit on some spots. Though the real thing that brought tears to her eyes were the bodies of the king and Arcadios in front of her.

"D-Daddy?" Hisui started to speak as tears poured down her dirtied face from the dust and debris. Not getting a response, she went to the bodies and attempted to shake them awake, hoping that they were only asleep, "DADDY! PLEASE WAKE UP!" However no response, which allowed a pit to form in the young girl's stomach as more tears, spilled from her eyes. She cried out as the young child began to sob uncontrollably.

"Ah… I see one managed to survive." A demonic voice was heard, causing the young child to look up only to see E.N.D standing only a few yards before her. More fear took hold of the young girl as tears continue to pour like a waterfall. E.N.D simply chuckled at seeing the pathetic state the green haired princess was in, "Don't worry. As much I would like to kill you, you are now basically the soul heir to the Fiore throne. So lighten up little girl. Hopefully you can make the Fiore Kingdom an actually challenge to me."

And with those words, the demon took off with his wings once again. All while his laugher was heard as the Fel Demon flew away from the palace and away from the city.

"Princess!" Hisui heard some guards who managed to get into the wreckage of the room shouted in concern and worry as they made their way to her.

Hisui couldn't stop herself from crying as one of the guards made sure that she was alright. The rest could only look on horror at the destruction that lay around them. The King was dead, as well as all of the ministers. This was truly a dark day for Fiore.

E.N.D is free. And the face of the world was about to change.

Did I mention that will be deaths in this? There will be deaths in this. In case you didn't know.

Hopefully I described E.N.D well, since I suck at describing things. In case anyone confused as to how E.N.D's his own thing, it's like Piccolo and Kami. While they are the same being, they are split into two beings. Same thing here with Natsu and E.N.D. More will be explained later on, but hopefully you all enjoying it. If you're not, can't say I blame you.

Also if anyone could come up with a better title for the story, that would be very appreciated.

See you all next time, whenever that will be.
